ROLL PACKAGE Filed Sept. l, 1938 Patented May 13, 1941 Edward J4. Heizer, westCaldKwellQN-vrassignor toyCongoleum-Nairn Inc., a corporation of New York leum rolls are usually wrapped inlpaper andthe wrapped roll is placed in asuitable crate.,` Small rolls of felt base yard goods are sometimes shipped Yusing no crate at all. For larger rolls, however, the felt base yard goods is usually put up in crates for the purpose of shipment. v

The crates which have Ausually been used here; tofore consist of end pieces at eachiendgof" the roll, the end pieces being connected togetherby slats extending longitudinally of theujollualong the outside thereof.

Referring to Figs. 1, 2 and 3 of the drawing, the package is in the form of a crate comprising end pieces indicated generally by the reference character IB and which may be made of a single part or of a plurality of parts. The end piece of the embodiment shown in the-drawing consists of parallel boards I and cross boards IIJ2 secured together by nails |03, this type of structure affording ample strength for carrying large rolls of linoleum, for example. The end piece can be made up in any other suitable way depending on the size of the package and the weight of the goods to be carried thereon. Slats II are secured to opposite margins of each of the end pieces I0 by any suitable means such as nails I2. The cross pieces or battens I3 are secured to the end pieces and/or the slats II by any suitable means such as nails I4.

, Within the crate is a roll I5 of sheet material which, as aforesaid, may be linoleum or felt base yard gOOds. The roll of material may be wound around a hollowcore member I6, as is common practice in the shipment of goods of this character and may be covered with a paper wrapping (not shown).

lAt one end of the crate is the support plate indicatedgenerally by the reference character II.

In this embodiment of my invention, the support Vginch thick and may range from about 10 inches to 13. inches square. Each chamfered part is about 2 inches wide and is at such an angle that the plate is decreased in thickness by a maximum of about 1%; inch at each margin.

Asis clearlyvapparent from Fig. 1, the charn- As above mentioned, crates are usually constructed with large slats on two opposite sides thereof and have cross battens on the other two sides. In handling a crate of this character, it is almost always moved from a horizontal position to a vertical position with one side having the long slats downward. For this reason, it is not essential to chamfer all four margins of the support plate. The support plate may be made with only two opposite marginal portions thereof chamfered, as shown in Fig. 3, and in such case the chamered portions of the support plate are placed in proximity to the long slats of the crate. The chamfered portions I8 are preferably cut across the grain rather than in a. direction with the grain so as to minimize the danger of splitting the support plate.

If desired, a modified form of support plate may be used such as the support plate shown in Fig. 4, the support plate in this figure being indicated generally by the reference character 20. The support plate includes the chamfered portions 2I which in this case are along each margin ofthe support plate. In order to guard against splitting of the support plate, a piece of ply wood 22 may be ladherently united to the upper surface of the support plate with the grain thereof set at an angle -to the grain of the body portion 23 of the support plate. This form of support plate is used advantageously in a carton, crate or similar container which is closed on all four sides.

The shock absorbing means may be placed at either or both ends of the package, as may be desired. For practical purposes it is only necessary, however, to place Ithe shock absorbing means at one end of the package, inasmuch as i In Fig.` 5 an alternate form of shock absorbing means is'shown. This form is shown to illustrate fered parts I8 afford a recess between the surface 'f5 of the support plate adjacent the plies of rolled sheet material and the outer-surface of the end piece. In Fig. 1 the action of lthe support Plate is illustrated when thev crate is dropped on a side edge .of the crate. It may be noted that the shock that. is received at the corner of the crate is transmitted to the support plate so as to be centered a substantial distance 'inwardly from the margin of the support plate. This is indicated by the-arrows in Fig. 1. The end piece I0 which protrudes outwardly from the base of the recess being of some material such as wood, has at least some resiliency. Also, the portion of the support plate overlying the recess possesses some resiliency, preferably being made of a material such as wood. Due lto the sluiting of the location of the strain imposed by a blow from the edge of the support plate toward the center of the support plate, the likelihood of injury resulting from blows and shocks of the character above mentioned is greatly reduced. The protection against injury from blows of this character is increased to some ext-ent by having the end piece or support plate, or both, made of a resilient material and by having the parts'thereof overlying the recess of such dimensionsith'at `the resiliency of the material is taken advantage of to reduce theharmful effects of shocksreceived at the `end edges of the crate. l.

the fact that it is not always essential to use a chamfered piece as part of the shock absorbing means. The crate shown in Fig. 5 may be similar to that shown in Fig'. 1 and may comprise the slats 24, the battens 25 and suitable end pieces (the end piece at one end only being shown and indicated generally by the reference character 26 and being composed of two boards 26', held in place by the slats and battens, e. g. by nails 262) In this modication the support plate 21 is in the form of a square piece of wood. The support plate'2'l is spaced from the end piece 26 by an intervening board 28 which has a substantially less width in at least one dimension than either the total width of the end piece or the total width of the support plate l2'I. The board 28 may be attached either to the end piece 26 or to the support plate 21 by any suitable means (not shown) soas to maintain the board in proper position relative to the other parts of the shock absorbing means at the end of the crate. In the first case the board 28 may be regarded as part of the end piece, andin the second case may be regarded as part of the support plate, it being apparent that the end piecey or the support plate or both may, as shown in Figs. 1 and 4 as well asY Fig. 5, be made of one piece or'of a plurality of pieces. In this construction it Will be noted that the board 28 serves to space the marginal portion of the support plate 21 from the marginal portion-of the end piece 26 by a recess extending inwardly from the marginal portion of the shock absorbing means between the upper surface of the support plate and the outer. surface of the fafafiigase forr'nof package the ends only of the roll of "rolled f materialjare protected :against injury. For this purpose an `end piece Vis u'sed in conjunction with ja support plate 3|. The endpiece'and supportjplate are of disk shapeandpreferably are attached to each other by suitable means such as: an adhesive. The margin 'of the 'support vplate isjlchamfered at'32fso fasto provide a recess between the margin of the support plate and the margin of the Vend piece.

` n order K to maintain the shock absorbing means in position, any suitable device may be 'use d. In the form shown an 'elongated bolt or rod l3,3 is used that is adapted to extend through a Yhollow core at the interior `of the roll I5 of rolled sheet material from the shock absorbing means at one end of the roll to an end piece (not shown) at the opposite end of the roll. The bolt may, as shown, pass through an opening 34 is the shock absorbing means, the nut 35 at the end of the bolt being placed in a suitable recess 36 so asfnot to protrude from the end of the shock absorbing means. In order to keep the shock ,abv',so'rbing means properly centered, a tapered plug 31 is preferably used that is adapted to t within the core I6 (see Fig. 1). The plug may be secured to the shock absorbing means by any suitable means such as nails 38.

When the type of shock absorbing means shown in Figs. 6 and 8 is used, the rolled sheet material is preferably first Wrapped in paper to protect the outer wall thereof. The shock absorbing assembly may then be placed at either or both ends of the rolled sheet material and secured in place by the bolt 33.

In order to make the construction more rugged and in order to prevent splitting, the end piece 30 is preferably made of ply wood. When the support plate is about 10 to 13 inches in diameter the end piece is preferably about 1/2 inch less in diameter than the diameter of the support plate and is about 1/4 inch in thickness. The support plate as shown is about 5/8 to 78 inch in thickness and the chamfer along the margin thereof is about 1% inches in width and is cut at such an angle that the thickness of the plate is reduced by about 1/2 inch at the outer edge. Moreover, the support plate 32 preferably has a piece of ply Wood 39 adherently united to the upper face thereof.

In Fig. 7 a modified form of this invention is shown In this case the end piece 40 is chamfered rather than the support plate. The support plate is in the form of a disk 4I of uniform thickness. The endA piece and support plate may be held together and maintained in proper position at the end of the rolled sheet material in the manner described above in connection with Figs. 6 and 8.

From the foregoing description, it is apparent that structures embodying this invention may take many different forms. The recess between the bottom of the end piece and the upper surface of the support plate may be made in a variety of different ways. The use of two pieces and chamfering one of them is to be preferred, al-

though any othermethod of undercutting one'v or the other, or both, of these parts may be employed to secure asimilar result. Moreoven'the recessmay be produced without cutting awayany member Aofjthe shock absorbing means, as illus-` trated in connection with Fig. l5, wherein the parts are selected and assembled so as to bring about a result which is comparable with that which may be obtained by chamfering or undercutting either the end piece or `support plate. The recess ispreferably such that the base of the recess is disposed inwardly from the margin of the support plate (orend piece) Aby a distance which is about 35% of thedistance from the margin of the supportplate (or base plate) to the center thereof. While these proportions for the parts of the `shock absorbing means is prefer` able, the proportions may be varied widely. n In order, however, to achieve the advantages of this invention to a commercially desirable extent the base of the recess should be 'disposed so :as to be atleast about 20% of the distance inwardly from the margin of the support plate (or base plate) to the center thereof. Since the rolledsheet material is usually of about the same 'outside diameter as the supportplate, the proportions vnamed apply toV the'rolled sheet material, as well as to the ysupport lplate therefor as to the Yextent to which the rolled sheet material should be undercutr by the recess in the shock absorbing means. It is to be understoodfthat the structures which have been shown and described hereinabovefhave been referred to merely for the purpose of affording illustrative examples of the practice of this invention and that the scope of this invention is to belimited only by the language of the appended claims.
